Installation guide

Non-recoverable hardware errors require immediate termination of normal
system operation and some form of corrective action (such as a system
reset).
Nonrecoverable hardware errors are reported to the operating system as a
machine check. The operating system will crash with a panic message,
such as the following:
panic (cpu 0): tlaser: MACHINE CHECK Non-recoverable hardware error
The system will then write out a crash dump, and reboot or halt
(depending on the setting of the auto_action console EV, which can be
BOOT or HALT). Some hardware errors require a complete system reset
before the operating system can be rebooted.
For system-wide hardware faults, the operating system will force a system
reset after writing the crash dump. After the reset is completed, if
auto_action is set to BOOT, the console firmware will automatically
reinitialize all partitions. Boot the operating system in each partition,
using the following commands:
P00>>>
boot
P##>>>boot
Otherwise, the system will halt and enter console mode (P00>>> prompt).
If this occurs, enter the following commands to restart partitions and
reboot the operating system (where N is the number of partitions):
P00>>>set lp_count N
P00>>>init
P00>>>lpinit
P00>>>boot
For each secondary partition, enter the boot command as follows:
P##>>>boot
For local hardware faults (contained within a partition), the operating
system running in the affected partition will unconditionally halt after
writing the crash dump. This allows other partitions to continue operating
until a shut down can be scheduled. Restarting the affected partition
requires a complete system reset, using the following procedure:
1. Shut down the operating system in each running partition as follows:
# /usr/sbin/shutdown -h +5 "Shutting down for error recovery"
2. At the primary console terminal, enter the following commands:
P00>>>set lp_count 0
P00>>>init
3. The following prompt is printed at the console:
